Pop-up items having pressure-sensitive adhesive

Abstract

To provide pop-up items a plurality of individual sheet material structures are die-cut in composite sheet material consisting of a front sheet and a rear liner sheet of release-coated material joined together by having a pressure-sensitive adhesive (PSA) pattern between the rear surface of the front sheet and the front surface of the rear liner sheet so that, upon separating the sheets, PSA releases from the release-coated rear sheet and adheres to the front sheet in at least desired regions. Some pop-up structures are formed with two generally symmetrical halves arranged about a fold-line. A folded structure results from the superimposition of one-half of the structure onto the other constituting a pop-up element in which two individual flag panels are joined together, as by being affixed to each other by PSA and in which there are at least two subpanels having exposed PSA-covered surfaces. When the pop-up element is placed between a pair of facing panels of a folded basepiece, the PSA-carrying subpanels become affixed to facing surfaces of the folded basepiece, and upon pivoting of the basepiece panels to the open position, the pop-up element assumes an attention-attracting, 3-dimensional configuration.

What is claimed is: 
     
       1. A pop-up item (311), which comprises a front sheet having a front surface and a rear surface,   a rear sheet, and   adhesive attaching said front and rear sheets to each other so that they can be separated without damage to either of said sheets,   said rear sheet having a front surface having releasing characteristics over at least part of its area so that pressure-sensitive adhesive located in the area will adhere to the rear surface of said front sheet when said front and rear sheets are separated from each other,   said front sheet having die-cut therein a pop-up structure (313) that contains a main front panel (315) that is connected along a fold-line (327) with a rear panel (325) having a different size and shape than said front panel (315), said front panel including a flag panel section and a base section that includes at least two legs (319) and a pair of die-cut apertures (323) of generally triangular shape, said legs being hinged to said flag panel section, and said pop-up structure having a pressure-sensitive adhesive coating on at least a portion of said rear surface in a region of said rear panel (325),   said flag panel section being formed with a central line of weakness (317) that extends perpendicular to said fold-line (327), and   said base section legs (319) being respectively hinged to said front panel section at angles of between about 30° and 60° to said central line of weakness,   so that, following separation of said die-cut pop-up structure (313) entirely from said rear sheet to expose said pressure-sensitive adhesive upon its rear surface, said die-cut pop-up structure can be folded along said fold-line (327) to superimpose said rear panel (325) upon said rear surface of said main front panel and affix one to the other and create a pop-up element of planar configuration including said flag panel section and said base section, with said rear panel having an associated exposed surface of generally triangular shape which carries pressure-sensitive adhesive (325a) located at each said aperture,   whereby said pop-up element can be affixed to a supporting surface or to a pair of hinged-together panels in a manner that said pop-up element assumes a three-dimensional configuration.   
     
     
       2. The pop-up item according to claim 1 wherein said rear panel (325) is hinged to an edge of one of said legs, and wherein said pressure-sensitive adhesive, which attaches said front and rear sheets, covers substantially the entire rear surface of said rear panel (325). 
     
     
       3. The pop-up item according to claim 2 wherein each of said legs (319) includes a hinged subpanel. 
     
     
       4. The pop-up item according to claim 1 wherein said rear panel (325) is hinged to lower edges of said legs (319) along said fold-line (327). 
     
     
       5. A pop-up item, which comprises a front sheet having a front surface and a rear surface,   a rear sheet, and   adhesive attaching said front and rear sheets to each other so that they can be totally separated from each other without damage to either of said sheets,   said rear sheet having a front surface having releasing characteristics over at least a preselected area and pressure-sensitive adhesive being located in at least some of said preselected area so that said pressure-sensitive adhesive will adhere to the rear surface of said front sheet when said front and rear sheets are separated from each other,   said front sheet having die-cut therein a pop-up structure that contains a main panel having a leg portion and an aperture region with said leg portion including a pair of parallel legs and said aperture region being located between said parallel legs and at least one panel connected thereto along a fold-line, said at least one panel having a different size and shape than said main panel, and the rear surface of said at least one panel carrying at least some of said pressure-sensitive adhesive, and   said at least one panel being hinged to an edge of said leg portion of said main panel along said fold-line,   so that, following separation of said die-cut pop-up structure entirely from said rear sheet to expose said pressure-sensitive adhesive upon said rear surface of said front sheet, said at least one panel can be folded rearward 180° about said fold-line so that there is surface-to-surface contact between said at least one panel and said rear surface of said main panel to create a pop-up element of planar configuration with at least some of said pressure-sensitive adhesive on said one at least panel being exposed through said aperture region and facing forward,   whereby said pop-up element can be affixed to a supporting surface or to a pair of hinged-together panels in such a manner that said pop-up element assumes a three-dimensional configuration.   
     
     
       6. The pop-up item according to claim 5 wherein said fold-line extends along a lateral edge of said leg portion. 
     
     
       7. A pop-up item, which comprises a front sheet having a front surface and a rear surface,   a rear sheet, and   adhesive attaching said front and rear sheets to each other so that they can be separated without damage to either of said sheets,   said rear sheet having a front surface having releasing characteristics over at least part of its area so that pressure-sensitive adhesive located in the area will adhere to the rear surface of said front sheet when said front and rear sheets are separated from each other,   said front sheet having die-cut therein a plurality of pop-up structures each of which contains a main front panel that has a rear panel section connected thereto along a fold-line, said rear panel section having a different shape and is smaller in size than said front panel, said front panel including two flag panel sections which have a common edge, along which said flag panel sections are hinged to each other, and a pair of parallel legs, each of said legs being hinged at one end to one of said flag panel sections and at another end to said rear panel section, and said legs being separated by an aperture region,   said pop-up structure having a pressure-sensitive adhesive coating on said rear surface of said rear panel section,   so that, following separation of one of said die-cut pop-up structures entirely from said rear sheet to expose said pressure-sensitive adhesive upon its rear surface, said die-cut pop-up structure can be folded along said fold-line to superimpose said rear panel section upon said rear surface of said main front panel and create a pop-up element of planar configuration including said two hinged flag panel sections and said parallel legs, with said pressure-sensitive adhesive being exposed through said aperture region,   whereby said pop-up element can be affixed to a supporting surface or to a pair of hinged-together panels in a manner that said pop-up element assumes a three-dimensional configuration.   
     
     
       8. The pop-up item according to claim 7 wherein said flag panel sections are hinged to each other along a longitudinal line of weakness, and wherein said pressure-sensitive adhesive covers substantially the entire rear surface of said rear panel section and is exposed through two triangular apertures provided by said aperture region.
